October 6, 2004
The invention refers to a fuel direct injection spark ignition type internal combustion engine, comprising a combustion chamber (2) and a pair of intake ports (4a',4b') extending to said combustion chamber (2), said intake ports (4a',4b') decreasing a distance therebetween as nearing said combustion chamber (2), each of said intake ports (4a',4b') having an axial center line that is inclined by an angle "&thetas;" relative to a first imaginary plane that includes a center line of an associated fuel injector (108a) and extends in parallel with a center line of an associated piston, said angle "&thetas;" satisfying the inequality of "0 DEG < &thetas; ≤ 15 DEG "; wherein said fuel injector (108a) is spaced from the center line of the associated piston, and wherein said first imaginary plane is inclined at an angle " alpha " to a second imaginary plane that includes the center line of the associated piston and is perpendicular to an axial line of an associated crankshaft.
